Canadarm Shuttle Remote Manipulator System

Since its maiden voyage aboard U.S. Columbia Unplanned exercises for Canadarm have included knocking a in 1981, the Shuttle Remote Manipulator System (SRMS), block of ice from a clogged waste-water vent that might have known as Canadarm, has demonstrated its reliability, endangered the shuttle upon re-entry, pushing a faulty antenna usefulness, and versatility and has provided strong, yet precise into place, and successfully activating a satellite that failed to go and delicate handling of its payloads. into proper orbit.

Canadarm was designed, developed and built by Spar Space In December, 1998 Canadarm played a critical role in the first Systems Robotics operation, now MD Robotics under contract assembly mission of the International Space Station, mating the to the National Research Council of . The first arm U. S. Unity node to the Russian-built Zarya. Canadarm will was Canada's contribution to NASA's . continue to play a vital role in the assembly of the space station. Subsequently, NASA ordered four additional units which have resulted in over $700 million in export sales for Canada. The Shuttle Remote Manipulator System consists of a shoulder, elbow and wrist joint separated by an upper and lower arm Canadarm has performed flawlessly for 20 years; placing boom. The shoulder joint has two degrees of freedom, the satellites into their proper orbit and retrieving malfunctioning elbow joint has one degree of freedom, and the wrist joint has ones for repair. Perhaps its notable mission was the up to three degrees of freedom. repair of the . Canadarm was used as a mobile work platform for astronauts during numerous space At a total weight of approximately 905 lbs., the Canadarm has walks required to repair the faulty telescope. Canadarm recently been upgraded to manoeuver payloads of up to 266,000 played a critical role retrieving the satellite, placing it in the kgs. (in the weightlessness of space). Canadarm uses an end cargo bay for repairs, and then re-deploying it. effector with a specially designed to place payloads in orbit. Notable Missions
